I am surprised no one else has responded so far. I am no expert but will try to help.

I suggest that you have a diagnostic test done by someone with a STAR diagnostic system. This is always good advice for these more modern cars often given on this forum.

My W203 C220cdi would just loose power on accelaration. Like someone closed thge fuel supply. It turned out that the lower air hose, a ~UKP60 part, had a crack and had to be replaced. Problem solved.
